Description

This early 1990s Koch Twintone represents the Dutch company's flagship design from their formative years. Built around a classic EL34 power section delivering 50 watts through a single 12" speaker, this amp offers the perfect balance of British-inspired midrange warmth and European refinement. The carefully selected preamp tube complement includes a low-microphonics 12AX7LM in the critical first gain stage, ensuring quiet operation and reduced handling noise.

Fun Fact

Koch amplifiers emerged in the early 1990s during a renaissance period for boutique tube amp builders. The Twintone was among Koch's first major successes, establishing their reputation for meticulous engineering and premium components. The use of carefully graded tubes, including low-microphonics preamp tubes, was ahead of its time and showed Koch's attention to professional studio requirements. The Celestion Vintage 30 has become one of the most recorded speakers in rock history, making this combination of Dutch craftsmanship and British speaker heritage particularly potent for both stage and studio applications.
